Chatbox is down
Our Web host recently discontinued support for PHP 5.2. This has broken the Chatbox, and it's not trivial to fix. The first thing I have to do is update the version of Drupal we are using, and this will require bringing down the entire site for a period of time so I can update it. Drupal is very hard to update (and the developers are proud of the lack of backward compatibility - don't get me started).
I will begin work on the problem this weekend, but I may not be able to resolve it this weekend. It's a lot of programming, and I've been having serious health problems (also affecting my ability to give access to new members). But I know how valuable the Chatbox is, and I will do everything I can to get it up and working again quickly.
